Ap licati fil d November 20, 1900. Serial No. 37,128. (No model.)

To all whom, it may concern.- pen-carrying arms 4 5, and consequentlythe Be it known that I, GEORGE S. TIFFANY, a movements of the pen P, arecontrolled by citizen of the United States, residing in the the drums 4.5, the rotation of which is in borough of Brooklyn, county of Kings, andturn controlled by the currents sent over line 55 5 State of New York,have invented certain from the transmittinginstrument, so that the newand useful Improvements in Telautoreceiving-pen P is caused to followthe movegraphs, fully describedand represented in the ments of and toreproduce the writing profollowing specification and the accompanyingduced by the transmitting-pen, as is well undrawings, forming a part ofthe same. derstood and as described, for example, in 60 This inventionrelates to improvements in my said two prior applications, to whichreftelautographic apparatus. erence is hereby made for a more detailedde- One branch of the present invention relates scription of theconstruction and operation of to a novel construction and arrangement ofthis apparatus. inking device for inking the pen in such The inkingdevice provided by the present 65 I apparatus as it arrives, forexample, at its invention consists of anink-recept-acle I,prounison-point or normal position, the inking vided with an opening 2'at its upper end, device provided by the present invention through whichit is filled and which isin turn for this purpose, though capable ofapplicaprovided with a stopper 2".

While theclosure of the ink-receptacle I to Referring to said drawings, 1 2represent a the atmosphere will prevent leakage of the pair of pen-armdrums, to which are conink through the supp1y-openingz' when the nectedby cords 3 in the usual way a pair of pen P is out of said opening aslight amount I00 pen-carrying arms 4 5, hinged together and of drip maytake place just as the pen P is becarrying a pen P. The movements ofthese ing introduced into or withdrawn from such into a waste-receptaclelocated beneath the ink-receptacle I, as shown in Fig. 2.

Any suitable form of receiving-pen may be used in connection with thisink-receptacle,

which is capable of entering opening 4? and contacting with the inktherein; but I prefer the one shown, which will now be described. Thispen consists of a stem p, provided at its writing end with intersectinglongitudinal slits 19, extending from side to side of the stem andupwardly some distance from the writing-point thereof,as shown in Fig.3. The stemp is also provided with a central inkholding orifice 19 abovethe writing-point of the pen and with which each of the slots 19communicates. This construction of pen is preferable,because of therapidity with which it may be supplied with ink, because of its largeholding capacity, and also because of the uniformity of flow therefromin writing.

The manner of using the ink-Well I and inking the pen P therefrom is asfollows: When the receptacle I has been filled with ink and then-closedby stopper t, the ink of course has a tendency to flow out through theside opening a As it enters said opening, however, it seals thereceptacle I, the outside atmosphere then permitting only enough ink toescape to cause the weight of the ink and the pressure of air within thereceptacle I to balance the pressure of the outside atmosphere, when theescape of ink will be arrested. The ink thus escaping will travel downthe lip i into the waste-receptacle i". The receiving-pen P being movedby drums 3 4 toward the ink-receptacle I its end will pass through theopening 13 into contact with the ink in the receptacle, when its slits19 and ink-holding orifice 19 will be supplied with ink by capillaryattraction. The capacity of the slits p and orifice 10 exceeds that ofthe opening 7?, so that as thepen thus takes up its supply of ink asufficient quantity of ink will be withdrawn from the opening 1' topermit a small quantity or bubble of air to enter the receptacle I tocompensate for the ink withdrawn, thus maintaining a constant supply ofink at the opening by gravity. The opening 11 and the end of the pen Pwhich enters said opening are, as will be observed, so proportionedrelatively to each other as to size and shape that when said pen restsin said opening, as it does when the apparatus is not in use, it willseal said opening, and thereby preserve the ink within the receptaclefrom the effects of the atmos phere.

The invention is not limited to the precise construction of inkingdevice and pen shown and described, and modifications and changes may bemade therein without departing from the spirit of the invention, broadlyconsidered.

What I claim is- 1. In a telautographic apparatus the combination with'apen and its carrying means, of an inking device comprising a closedreceptacle provided with aside opening adapted for the passage of theink-receiving end of the pen into contact with the ink within thereceptacle, substantially as described.

2. In a telautographic apparatus the combination with a pen and itscarrying means, of an inking device comprising a closed receptacleprovided with a side opening adapted for the passage of theink-receiving end of the pen into contact with the ink within thereceptacle, the ink-holding capacity of said opening being less thanthat of the pen, substantially as described.

3. In a telautographic apparatus the combination with a pen and itscarrying means, of an ink device comprising a closed receptacle providedwith a side opening adapted for the passage of the ink-receiving end ofthe pen into contact with the ink within the receptacle, awaste-receptacle beneath said opening and means for conducting inkdripping from said opening into said waste-receptacle, substantially asdescribed.

4. In a telautographic apparatus the combination with its pen-carryingmeans, of a pen comprising a stem the writing end whereof is slitlongitudinally and an inking device comprising a closed receptacleprovided with a side opening adapted for the passage of the ink-receiving end of the pen into contact with the ink within the receptacle,substantially as described.

5. In a telautographic apparatus the combination with its pen-carryingmeans, of apen comprising a stem the writing end whereof 'is providedwith longitudinal intersecting slits and an inking device comprising aclosed 1 receptacle provided with a side opening adapt ed for thepassage of the ink-receiving end of the pen into contact with the inkwithin the receptacle, substantially as described.

6. In a telautographic apparatus the combination with its pen-carryingmeans, of apen comprising a stem the writing end whereof is providedwith longitudinal intersecting slits and with an inner ink-holdingorifice communicating with said slits and an inking device comprising aclosed receptacle provided with a side opening adapted for the passageof the ink-receiving end of the pen into contact with the ink within thereceptacle, substantially as described.

7. In a telautographic apparatus the combination with its pen-carryingmeans, of apen comprising a stem the writing end whereof is slitlongitudinally and provided with an inner ink-holding orificecommunicating with said slit portions, and an inking device comprisingaclosed receptacle provided with a side opening adapted for the passageof the ink-recei ving end of the pen into contact with 1 2 being soproportioned relatively to each other that when the latter is in saidopening it substantially seals the same, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing r5 witnesses.
